dust

Karl Gordon (STScI) came by on Friday to give the astrophysics seminar. He spoke about dust in star-forming regions and evidence for processing of the dust by massive stars. In conversations before his talk, Moustakas and I realized that we could measure the spectral dust law from SDSS spectra of stars; I did a quick-and-dirty job of that this weekend. I find that the dust law is in the data at huge significance. Now we are trying to figure out if it is worth doing right and publishing.
